To provide policy and procedures for the evaluation and mitigation of ad-verse environmental impacts to wet-lands and na

9、tural habitat resulting from Federal-aid projects funded pur-suant to provisions of title 23, U.S. Code. These policies and procedures shall be applied by the Federal High-way Administration (FHWA) to projects under the Federal Lands High-way Program to the extent such appli-cation is deemed appropr

10、iate by the FHWA. 777.2 Definitions. In addition to those contained in 23 U.S.C. 101(a), the following definitions shall apply as used in this part: Biogeochemical transformations means those changes in chemical compounds and substances which naturally occur in ecosystems. Examples are the car-bon,

11、nitrogen, and phosphorus cycles in nature, in which these elements are in-corporated from inorganic substances into organic matter and recycled on a continuing basis. Compensatory mitigation means res-toration, enhancement, creation, and under exceptional circumstances, pres-ervation, of wetlands, w

12、etland buffer areas, and other natural habitats, car-ried out to replace or compensate for the loss of wetlands or natural habitat area or functional capacity resulting from Federal-aid projects funded pur-suant to provisions of title 23, U.S. Code. Compensatory mitigation usu-ally occurs in advance

13、 of or concurrent with the impacts to be mitigated, but may occur after such impacts in spe-cial circumstances. Mitigation bank means a site where wetlands and/or other aquatic re-sources or natural habitats are re-stored, created, enhanced, or in excep-tional circumstances, preserved, ex-pressly fo

I (4111 Edition) 77

15、7.2 compensatory mitigation in advance of authorized impacts to similar re-sources. For purposes of the Clean Water Act, Section 404 (33 U.S.C. 1344), use of a mitigation bank can only be authorized when impacts are unavoid-able. Natural habitat means a complex of natural, primarily native or indige

16、nous vegetation, not currently subject to cultivation or artificial landscaping, a primary purpose of which is to provide habitat for wildlife, either terrestrial or aquatic. For purposes of this part, habitat has the same meaning as nat-ural habitat. This definition excludes rights-of-way that are

17、acquired with Federal transportation funds specifi-cally for highway purposes. Net gain of wetlands means a wetland resource conservation and management principle under which, over the long term, unavoidable losses of wetlands area or functional capacity due to highway projects are offset by gains a

18、t a ratio greater than 1:1, through res-toration, enhancement, preservation, or creation of wetlands or associated areas critical to the protection or con-servation of wetland functions. This definition specifically excludes natural habitat, as defined in this section, other than wetlands. On-site,

19、in-kind mitigation means com-pensatory mitigation which replaces wetlands or natural habitat area or functions lost as a result of a highway project with the same or like wetland or habitat type and functions adjacent or contiguous to the site of the impact. Practicable means available and capa-ble

20、of being done after taking into con-sideration cost, existing technology, and logistics, in light of overall project purposes. Service area of a mitigation bank means that the service area of a wet-land or natural habitat mitigation bank shall be consistent with that in the Federal Guidance for the

21、Establish-ment, Use and Operation of Mitigation Banks (60 FR 58605, November 28, 1995), i.e., the designated area (e.g., water-shed, county) wherein a bank can be expected to provide appropriate com-pensation for impacts to wetlands and/ or other aquatic or natural habitat re-sources. Wetland or hab

22、itat enhancement means activities conducted in existing wet-lands or other natural habitat to achieve specific management objec-tives or provide conditions which pre-viously did not exist, and which in-crease one or more ecosystem func-tions. Enhancement may involve trade-offs between the resource s

23、tructure, function, and values; a positive change in one may result in negative effects to other functions. Examples of activities which may be carried out to enhance wetlands or natural habitats include, but are not limited to, alteration of hy-drologic regime, vegetation manage-ment, erosion contr

24、ol, fencing, inte-grated pest management and control, and fertilization. Wetland or habitat establishment period means a period of time agreed to by the FHWA, State DOT, and U.S. Army Corps of Engineers, as necessary to es-tablish wetland or natural habitat functional capacity in a compensatory miti

25、gation project sufficient to com-pensate wetlands or habitat losses due to impacts of Federal-aid highway projects. The establishment period may vary depending on the specific wetland or habitat type being developed. Wetland or habitat functional capacity means the ability of a wetland or nat-ural h

26、abitat to perform natural func-tions, such as provide wildlife habitat, support biodiversity, store surface water, or perform biogeochemical transformations, as determined by sci-entific functional assessment. Natural functions of wetlands include, but are not limited to, those listed by the U.S. Ar

27、my Corps of Engineers at 33 CFR 320.4(b)(2)(i) through (viii). Wetland or habitat preservation means the protection of ecologically impor-tant wetlands, other aquatic resources, or other natural habitats in perpetuity through the implementation of appro-priate legal and physical mechanisms. Preserva

28、tion of wetlands for compen-satory mitigation purposes may in-clude protection of upland areas adja-cent to wetlands as necessary to ensure protection and/or enhancement of the aquatic ecosystem.

30、9 CFR part 7. Wetland or habitat restoration means the reestablishment of wetlands or nat-ural habitats on a site where they for-merly existed or exist in a substan-tially degraded state. Wetland or wetlands means those areas that are inundated or saturated by surface or ground water at a fre-quency

31、 and duration to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally in-clude swamps, marshes, bogs and simi-lar areas. Wetlands or habitat mitigation credit means a unit of wetlands or habita

The justification for the cost of proposed mitigation measures should be considered in the same context as any other public ex-penditure; that is, the proposed mitiga-tion represents a reasonable public ex-penditure when weighed against other social, econo

Mitigation measures shall give like consideration to traffic needs, safety, durability, and economy of maintenance of the highway. (b) It is FHWA policy to permit, con-sistent with the limits set

48、771. 777.9 Mitigation of impacts. (a) Actions eligible for Federal fund-ing. There are a number of actions that can be taken to minimize the impact of highway projects on wetlands or nat-ural habitats. The following actions qualify for Federal-aid highway fund-ing: (1) Avoidance and minimization of

49、impacts to wetlands or natural habi-tats through realignment and special design, construction features, or other measures. (2) Compensatory mitigation alter-natives, either inside or outside of the right-of-way. This includes, but is not limited to, such measures as on-site mitigation, when that alternative is determined to be the preferred ap-proach by the appropriate regulatory agency; improvement of existing de-graded or historic wetlands or natural
